Study Notes
Mass Spectrometry
- A mass spectrum plot displays the distribution of ions by their mass-to-charge ratio, providing information on the molecular weight and structure of the sample.
Ion Separation and Ionization
- In mass spectrometry, ions are separated based on their mass-to-charge ratio, typically using a magnetic field or electric field.
- The purpose of ionizing the sample is to create charged particles (ions) that can be separated and detected by the mass spectrometer.
- Ionization is typically achieved by bombarding the sample with high-energy electrons or photons, causing some of the sample's molecules to become positively charged.
Mass Spectrum Analysis
- A mass spectrum can be used to determine the molecular weight, structure, and identity of the sample.
- Mass spectrometry determines the molecular weight and structure of a sample by separating and detecting ions based on their mass-to-charge ratio.
Presentation of Results
- Mass spectrometry results are typically presented as a mass spectrum, which is a plot of the distribution of ions by their mass-to-charge ratio.
